I'm not sure about the gains, but i know that my chip made a HUGE difference. And as for problems, I dont have many...

 

i wondered what years were affected by the sludge the worst.

my 2001 doesnt show a lick of sludge under the valve cover, so aslong as you keep up with a good quality oil change every 3k no worries

 

Same here, besides changing the normal wear and tear parts.. As far as any other problems, I've been lucky enough not to have any.. =)

 

Thanks for the replies, Anything i should know about for the 02'? I am looking at both an 01 and an 02'

 

I don't have any sludge under my valve cover. I change the oil every 10,000 mi. with Mobil 1 0W-40. I have 85K mi. , only repair a rear wheel bearing.

 

Well the body style changes in the 02 Model..

 

B5 A4's are smooth go with them..............

 

01 and 02 is the same engine really. The body style changes from those years and IMO I feel the B5 (96-01) is a better looking car.

 

I also agree the b5 is the better looking, performing car. The aeb (97-99.5) has the big port head, as well as drive by cable (easier to tune) the newer ones did have 20 more hp but once chipped or ko4'd they are about the same

 

Yea..B5 for sure...couldnt be happier wiht my 2000. Although a flashloader would be nice...but they dont ahve one for me yet[:@]
